Winter Games vehicle (4)
I believe the answer is:
luge
'winter games vehicle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for luge that I've seen before include "Glue for a one-man sledge" , "Winter Olympic event" , "Form of toboggan" , "Olympics sledge" , "Light toboggan" .)
